Learning Latent Jet Structure [PDF]

open access: yesSymmetry, 2021
We summarize our recent work on how to infer on jet formation processes directly from substructure data using generative statistical models. We recount in detail how to cast jet substructure observables’ measurements in terms of Bayesian mixed membership models, in particular Latent Dirichlet Allocation.

Synthesis of a novel photoactivatable glucosylceramide cross-linker

open access: yesJournal of Lipid Research, 2016
The biosynthesis of glucosylceramide (GlcCer) is a key rate-limiting step in complex glycosphingolipid (GSL) biosynthesis. To further define interacting partners of GlcCer, we have made a cleavable, biotinylated, photoreactive GlcCer analog in which the ...

Exact Learning Augmented Naive Bayes Classifier

open access: yesEntropy, 2021
Earlier studies have shown that classification accuracies of Bayesian networks (BNs) obtained by maximizing the conditional log likelihood (CLL) of a class variable, given the feature variables, were higher than those obtained by maximizing the marginal ...

Learning with structured sparsity

open access: yesProceedings of the 26th Annual International Conference on Machine Learning, 2009
This paper investigates a new learning formulation called structured sparsity, which is a natural extension of the standard sparsity concept in statistical learning and compressive sensing. By allowing arbitrary structures on the feature set, this concept generalizes the group sparsity idea that has become popular in recent years.

Variable Chromosome Genetic Algorithm for Structure Learning in Neural Networks to Imitate Human Brain

open access: yesApplied Sciences, 2019
This paper proposes the variable chromosome genetic algorithm (VCGA) for structure learning in neural networks. Currently, the structural parameters of neural networks, i.e., number of neurons, coupling relations, number of layers, etc., have mostly been

Learning Bayesian Networks That Enable Full Propagation of Evidence

open access: yesIEEE Access, 2020
This paper builds on recent developments in Bayesian network (BN) structure learning under the controversial assumption that the input variables are dependent.

ISHS-Net: Single-View 3D Reconstruction by Fusing Features of Image and Shape Hierarchical Structures

open access: yesRemote Sensing, 2023
The reconstruction of 3D shapes from a single view has been a longstanding challenge. Previous methods have primarily focused on learning either geometric features that depict overall shape contours but are insufficient for occluded regions, local ...

Structured Priors for Structure Learning

open access: yesCoRR, 2012
Traditional approaches to Bayes net structure learning typically assume little regularity in graph structure other than sparseness. However, in many cases, we expect more systematicity: variables in real-world systems often group into classes that predict the kinds of probabilistic dependencies they participate in.

Multiple conformations facilitate PilT function in the type IV pilus

open access: yesNature Communications, 2019
Bacterial type IV pilus-like systems catalyse the formation of pilin fibres but it is unknown how they are powered. Here, the authors present crystal and cryo-EM structures of the hexameric motor ATPases PilB and PilT from Type IVa Pilus that reveal ...
